    Tinkering – FPGA

    If you have been a long time follower, you might remember a flurry of activity in late 2015 and early 2016 when I was diving into tinkering with an Arduino board. At the time, I was building bits and pieces to make a remote weather station. (that was derailed by an unrelated life change, but I have slowly gotten back into it.)

    The Arduino is interesting as it is a pretty complete SOC, with memory, microcontroller, CPU, and a pretty robust set of digital and analog IO’s. Plenty of cool things you can do with it, and it is really simple to program. Ordinary C code, solid libraries, and third parties make a pretty complete set of sensors and widgets, with libraries to support them. (more…)

    My mother inlaw has been in an assisted living community for a couple of years. As part of the move in, my brother inlaw got her this service called “Grandcare” that provides a touchscreen PC with a very customized user interface.

    The first PC that was sent to her room was a pretty large HP Envy 20 AIO touchscreen system. First manufactured in 2012, it has a HD resolution, 20″ touch screen display, and is licensed for Windows 8/8.1 (there is no sticker on it, the OEM code is in the BIOS ROM.) It has a 3.1 GHz Pentium G870 chip, which is a dual core, 4 thread processor with integrated Intel HD graphics. Just fine for this system. (more…)
